Exodus 23:13
King James Version
“And in all that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.”
Context
10And six years thou shalt sow thy land, and shalt gather in the fruits thereof:
11But the seventh thou shalt let it rest and lie still; that the poor of thy people may eat: and what they leave the beasts of the field shall eat. In like manner thou shalt deal with thy vineyard, with thy oliveyard.
12Six days thou shalt do thy work, and on the seventh day thou shalt rest: that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger, may be refreshed.
13And in all that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth.
14Three times thou shalt keep a feast unto me in the year.
15Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)
16And the feast of harvest, the firstfruits of thy labours, which thou hast sown in the field: and the feast of ingathering, in the end of the year, when thou hast gathered in thy labours out of the field.
